Met a new instrument Wako (和胡)

I met a new instrument named Wako (和胡) the other day. It's similar to erhu (二胡). It's made from a Japanese instrument maker and played by a Wako player, Satochiki (里知帰).

I got help from the Bing Ch

二胡に似た和胡という楽器の存在を知って、興奮ぎみに調査中。二胡も大好きやけど、和胡の音色も美しい。音色の魅力は言葉では言い表しにくい。
